Window and manufacturing method thereof

Abstract

A window includes a first glass substrate having a first thickness and including a first flat part and a second flat part, which face each other, with a first curved part disposed therebetween; a second glass substrate having a second thickness, disposed at an inner side of the first glass substrate, and including a third flat part and a fourth flat part, which face each other, with a second curved part disposed therebetween; and a light shielding layer disposed between the first glass substrate and the second glass substrate or disposed at an inner side of the second glass substrate.

What is claimed is: 
     
       1. A window comprising:
 a first glass substrate having a first thickness and comprising a first flat part and a second flat part, which face each other, with a first curved part disposed therebetween; 
 a second glass substrate having a second thickness, disposed at an inner side of the first glass substrate, and comprising a third flat part and a fourth flat part, which face each other, with a second curved part disposed therebetween; 
 a light shielding layer disposed between the first glass substrate and the second glass substrate; and 
 an adhesive layer disposed between the first glass substrate and the second glass substrate, 
 wherein each of the first glass substrate and the second glass substrate comprises:
 a first area which overlaps the light shielding layer in a plan view; and 
 a second area which does not overlap with the light shielding layer, 
 
 wherein the first area surrounds the second area, 
 wherein the adhesive layer overlaps the second area and not overlap the first area, and 
 wherein the second glass substrate itself is rigid in a folded state. 
 
     
     
       2. The window of  claim 1 , wherein the first glass substrate has a thickness less than a thickness of the second glass substrate. 
     
     
       3. The window of  claim 2 , wherein the first glass substrate has the thickness in a range from about 20 μm to about 100 μm, and the second glass substrate has the thickness in a range from about 100 μm to about 1000 μm. 
     
     
       4. The window of  claim 1 , wherein the light shielding layer has a thickness in a range from about 5 μm to about 10 μm. 
     
     
       5. The window of  claim 1 , wherein the second curved part has an inner radius of curvature in a range from about 3 millimeters (mm) to about 4 mm. 
     
     
       6. The window of  claim 1 , wherein an average distance between the third flat part and the fourth flat part is in a range from about 6 mm to about 8 mm. 
     
     
       7. A window comprising:
 a first glass substrate comprising a first flat part and a second flat part, which face each other, with a first curved part disposed therebetween; 
 a light shielding layer disposed on an outer side of the first glass substrate; and 
 an adhesive layer disposed on an outer side of the first glass substrate, 
 wherein the first glass substrate comprises:
 a first area which overlaps the light shielding layer in a plan view; and 
 a second area which does not overlap with the light shielding layer, and the first area surrounds the second area, 
 
 wherein the adhesive layer overlaps the second area and not overlap the first area, and 
 wherein the first glass substrate itself is rigid in a folded state. 
 
     
     
       8. The window of  claim 7 , further comprising a second glass substrate which is disposed at an outer side of the light shielding layer,
 wherein the second glass substrate comprises a third flat part and a fourth flat part, which face each other, with a second curved part disposed therebetween 
 wherein the second glass substrate is thinner than the first glass substrate. 
 
     
     
       9. The window of  claim 8 , wherein the first curved part has an outer radius of curvature equal to or less than an inner radius of curvature of the second curved part.
